Abstract
A method of making intercell connections in a lead-acid storage battery. The battery has a plurality of pairs of vertical risers of lead or other readily feasible material, each pair sandwiching an electrically insulating vertical partition. The method comprises forming a horizontal hole in a partition, squeezing together such as by hydraulic cylinders, a pair of risers against its corresponding partition and applying coils energized by high frequency electrical current against the outer surfaces of the risers adjacent the hole and simultaneously squeezing together said pair of risers against its partition so as to fuse the riser material adjacent the hole and introduce it through and fill the hole. High quality readily reproducible intercell connections are thus formed successively throughout the battery.
